What’s the Developing Trend of Belt Conveyor?

Low-end products occupy a large proportion in belt conveyor industry, with the daily improvement of the technology, changes would be made in the future development of the belt conveyor manufacturer. The forthcoming belt conveyor system should contain the following 5 features:

1. High conveying capacity and speed;

This also means high productivity and low manufacture cost in unit time.

2. Long service time;

The abrasion between the conveyor belt and the roller is the main reason that restricts the service time of the belt conveyor. It needs further improvement in the future design.

3. Low cost of production;

Adopting non-roller support or non-contact support is the most efficient way to lower the belt conveyor cost.

4. Low power consumption ;

80% of the belt conveyor power is consumed in friction wastage. To reduce friction wastage, the most efficient way is adopting non-contact type belt conveyor.

5. More intelligent.

It would be closely associated with microcomputer and intelligent operation would be reached in the future.

Brief Introduction of Belt conveyor Sweeper Type

Belt conveyor sweeper is one important part of belt conveyor, there are totally three types of belt conveyor sweeper: carbide belt conveyor sweeper, H type alloy rubber belt conveyor cleaner, P type alloy rubber belt conveyor cleaner.

1.Carbide belt conveyor sweeper

The Carbide belt conveyor sweeper is installed at the head pulley with the texture of scraper adopting carbide alloy. There are generally two types of it: single piece belt conveyor sweeper and double pieces belt conveyor sweeper. It realizes thoroughly material cleaning by changing the pressure beard by the conveying belt from the scraper through adjusting the balancing weight.

2.H type alloy rubber belt conveyor cleaner

It is installed at the head place of the pulley close to the conveying belt, principally applying the rubber elasticity. Meanwhile, the scraper texture is changed to Carbide scraper from rubber. It is placed close to the surface of the conveyor belt after the separation of the material with the conveyor belt.

3.P type alloy rubber belt conveyor cleaner

It is also installed at the head place of the pulley with the installation site similar to that of the spring sweeper. Besides, it shares the sweeping principle with the H type alloy rubber cleanser.

Step Analysis for the Installation Process of Belt Conveyor

There are seven steps in the installation process of belt conveyors, here are some tips analyzed by experts from PK machinery.

1 .Installation of the belt conveyor landing leg and intermediate frame

Please confirm the Centerline by using the theodolite before installation, then according to the centerline to find pile point location of each landing leg. If there is embedded iron, adjustment should be made according to the location of the embedded iron in order to facilitate the installation, each landing leg should be firmly welded with the embedded iron.

2 .Installation of the counterweight device

In this process we need to ensure the parallelism between the two force columns, and meanwhile ensure its verticality. Considering the safety, protective railings shall be immediately installed after finishing the installation of this device.

3 .Installation of the headstock, tailstock and drive device base

Firstly we should verify the install elevation and confirm the centerline. Then pay attention to the sizing block location and its number not more than 5 blocks. The thinner sizing block should be placed among the thicker ones and be firmly welded.

4 .Installation of the roller and carrier roller

Before the installation, we should check the rotary condition of the bearing and repair or change it in time if there is any problems in the rotating.

5 .The Unit Installation

The unit axis deviation is 0.02 mm; the radial error of coupling is 0.05 mm, the Clearance between the half couplings is 3 ~ 5 mm. the levelness and usage of the sizing block should also meet the specification requirements.

6 .The belt installation

The belt installation should be operated by the manufacture or the professional.

Suggestions on Lubricating Points and System of Belt Conveyor

As we all know, regular maintenance and proper maintaining methods is essential in the daily operation of the belt conveyor.  Poor maneuverability would appear if the equipment has been used for long time, therefore we need to clean and lubricate the conveyor. Here our experts share some suggestions on the Lubricating points and methods with you.

  1.Lubricating Points

The lubricating points contains motor bearings, roller bearings, shaft sleeve bearings, bearing, gear reducer, the roller bearing and so on.

Roller is the most commonly used rotating parts of the belt conveyor, its quality and service life has a great influence on the belt conveyor running efficiency and reliability. The roller is equipped with bearing. Due to the gear reducer, its structure is relatively concentrated, with many parts needed lubrication, such as bearing pedestal, bearing gear and the meshing gear. In contrast, the structure of the roller bearing and motor bearings is relatively dispersed, especially the belt conveyor with long conveying distance. Each part is singly equipped with lubricating device.

2.Lubricating system

•  Manual lubrication system

The manual cleaning separator grease station should be installed in the center of the lubricating system. The distributer should be fixed in the device which needs lubrication, with its installing station convenient for observation and maintenance. Cold rolled seamless steel tube can be generally chosen as to the texture of the lubricating pipeline.

• Electric lubrication system

The electric lubrication is generally installed in the central part of the electric lubrication system, and usually need to set up special lubricating state with assurance of tidy and clean. The differential pressure switch is generally installed at the end of the main pipe line, behind the switch there should be installed a distributor. The piezometer however is commonly installed near the switch. The requirement for the texture is same as that of the Manual lubrication system.

Do you Know About the Installation and Adjustment of the Pull Cord Switch on the Belt Conveyor?

Do you know about the installation and adjustment of the Pull Cord Switch on the belt conveyor?
Pull Cord Switch is commonly known as "emergency stop switch". When the belt conveyor need downtime, Pull Cord switch action will stop the conveyor. Pull Cord Switch can be divided into manual reset and automatic reset. Automatic reset: after action, it can automatically return to the initial position, may lead to error start. Manual reset: after action, the self-locking device can maintain the operating position, it need to manually reset handle to make its return to the initial position.
Pull Cord Switch should be installed on both sides of the conveyor where has a maintenance channel, installation position should ensure that the maintenance person operates conveniently in the event of an emergency.
1.Pull Cord Switch is fixed on the rack.
2.The distance of the two switches on one side is about 50 m, the two switches are connected by the diameter 4mm of wirerope, elastic should be moderate.
3.To reduce the influence of the weight of wire rope on switches, we install supporting ring on the frame every 3 m to support the steel wire rope.
4.The other end of the rope is in tension spring (with rope buckle), In a way not affecting the normal use, using tightener to pull the rope tension on both sides, and to ensure that tension is balanced on both sides.
(Note: The climbing section of the conveyor, should try to shorten the Switch spacing distance and the pull rope length.)

What are Types Of Belt Conveyor Pulley Surface Coating?

 Belt conveyor pulleys play an important role in belt conveyor, such as transmitting traction for belt conveyor; changing direction of the conveyor belt; increasing the friction etc. Pulley surface coating on one hand,it can protect the conveyor belt from debris hurt ,on the other hand it can increase the friction between the conveyor belt and pulley, ensure normal conveyor belt running direction. 
There are 3 types of surface coating which we commonly used: smooth surface coating, herringbone coating, diamond coating. Usually, Smooth surface coating is used for bend pulley which can increase the service life of pulley, reduce the friction between conveyor belt and pulley cylinder, then the pulley surface will not be corroded by material. Herringbone coating is commonly used for the transmission pulley, since the transmission pulley drives running of conveyor, strong friction will generate on the transmission pulley, so we adopt herringbone coating. Herringbone coating is suitable for the belt conveyor which conveys material in one way,while the diamond coating can be applied to the reversible belt conveyor, which can realize the unloading material bidirectionally.

Belt Conveyor Trippers Were on Their Way to Thailand

“All products meet clients’ specific requirements” is what we have promised.

Right before 5 days ago, we reached an agreement with our clients from Thailand, promising to deliver belt conveyor with tripper and circular vibrating screen what they had reserved. The belt conveyor with tripper refers to a particular equipment worked for wooden chip production line which will be settled at the top of warehouse to reach a maximum utilization rate of its space. 

Besides, their belt width are 1000mm and 650mm, length 25mm and 42mm.While circular vibrating screen is available for separating wooden chip with a size scale larger than 50mm, and stone size smaller than 4mm.

In addition, our clients are in need of metal detector, permanent magnet and drum separator as well. The permanent magnet settled at the feeding end is designed for isolating metals from material, while metal detector and drum separator are applied to eliminate the metal appeared in the production line.

Belt Conveyor Safety Operation Regulation

Belt conveyor is a kind of continuous conveying equipment. Can be widely used for quarry, coal, steel, chemical and other kinds of industries. Operating the belt conveyor safety, not only can make sure the safety of the operator, but also can longer the service life of the belt conveyor. PK machinery will introduce the safety operation regulation of the belt conveyor:

1. The belt conveyor should start without load and should not feed material until it operating regularly. Forbidden feed the material before starting.
2. Fixed belt conveyor should be installed on fixed foundation. Before the mobile belt conveyor operating officially, wheels should be holdback through triangular wedge or brake. To avoid move during operating, there should be an 1 meter channel between each machine if multi-set belt conveyor operating parallelly.
3. Before using the belt conveyor, we must check whether all the moving parts, belt buckles and bearing device is normal or not; whether the protective equipment is completely or not. Belt tensioning degree should be adjusted to the appropriate level before starting.
4. Forbidden stand on the conveyor belt.
5. If multiply sets belt conveyor connection with each other one by one, we should start the one in discharge end first, then start the other sets according to their order. You can feed the material once all of the equipment operating normally.

Matters should be noted during belt sway switch installation and adjustment

Matters should be noted during belt sway switch installation and adjustment 

Belt sway switch is used to check the belt running deviation of the belt conveyor, it is a safe protection device of automatic alarm and stop when the belt running deviation appears.Belt sway switch is fixed on the conveyor belt bracket, action bar is at the side of the belt, when the belt running deviation appears, force the action bar deviation, and touch the alarm micro switch. If the belt running deviation continues,will touch another group of contact, and the conveyor will be protective to stop.
In the installation and adjustment of belt sway switch, what matters should we pay attention to? PK Machinery will answer for you!
1. Belt sway switch should be located on both sides of the conveyor belt, the vertical roll should be vertical with conveyor belt edge flat, and both sides of the conveyor belt are located at 1/3 height of vertical roll.
2.The distance between the vertical roll of belt sway switch and the normal position of conveyor belt should be 50 ~ 100 mm.
3.The quantity of belt sway switch ought to be determined according to the length of the conveyor, types and arrangement. Commonly it is located on the conveyor head, tail, convex segment, concave segment and the middle position.(Note: when the conveyor is longer, a pair of belt sway switch can be located every 30 ~ 35 m.)
4.Belt sway switch connects the conveyor middle frame through the mounting bracket, switch bracket will be welded with conveyor frame after the installing completion of the conveyor, and belt sway switch shall be bolted in the bracket.

Application of Sidewall Belt Conveyor in Thermal Power Plant

1.Requirements
Sidewall belt conveyor is the major equipment to convey coal and lime-ash in thermal power plant. Therefore it has high requirements for the security of equipment. Generally speaking, the whole transit line is equipped with twin channel sidewall belt conveyor, one is put into use, another is as standby application device. Thus, this coal handling system must be equipped with sidewall belt conveyor with 2500m-3000m length. Applying sidewall belt conveyor to thermal powder plant, it can not only simplify procedure, but also save cost.
2.Features
Due to power plant has high requirements for the security of equipment, technical requirements of sidewall belt conveyor are as follows:
1) It has different requirements for belt conveyor when it used to receive, convey or discharge materials. For instance, if the belt conveyor is used to receive materials, the belt speed of it shouldn’t be too high. If it is used to convey materials, it requires that trough angle of idler decrease properly. If plow discharger is put into use, the cover rubber of belt surface should be thicken properly. 
2)The belt speed should be low. Belt conveyor is mostly arranged in workshop, so it has high requirements for coal dust control. According to domestic and foreign practical experience, it’s better to adopt lower speed.
3)After installation of this machine, it seldom changes its layout.
4)Different coal type has different requirements for belt conveyor. For example, large coal particle size needs impact idler with high quality. Coal with less water and more dust needs guide chute with good sealing.
